My Readers will soon observe what a great Compass of real and useful Knowledge this Science includes; wherein, although Nature, assisted by a Genius, may be very instrumental, yet a strong Memory and constant Application, together with Example and Precept, will be highly necessary: For these Reasons I have often wished, that certain Male and Female Instructors, perfectly versed in this science, would set up Schools for the Instruction of young Ladies and Gentlemen therein. I remember about thirty Years ago, there was a _Bohemian_ Woman, of that Species commonly known by the name of _Gypsies_, who came over hither from _France_, and generally attended ISAAC the Dancing-Master when he was teaching his Art to Misses of Quality; and while the young Ladies were thus employed, the _Bohemian_, standing at some distance, but full in their Sight, acted before them all proper Airs, and turnings of the Head, and motions of the Hands, and twistings of the Body; whereof you may still observe the good Effects in several of our elder Ladies. After the same manner, it were much to be desired, that some expert Gentlewomen gone to decay would set up publick Schools, wherein young Girls of Quality, or great Fortunes, might first be taught to repeat this following System of Conversation, which I have been at so much pains to compile; and then to adapt every Feature of their Countenances, every Turn of their Hands, every Screwing of their Bodies, every Exercise of their Fans, to the Humour of the Sentences they hear or deliver in Conversation. But above all to instruct them in every Species and Degree of Laughing in the proper seasons at their own Wit, or that of the Company. And, if the Sons of the Nobility and Gentry, instead of being sent to common Schools, or put into the Hands of Tutors at Home, to learn nothing but Words, were consigned to able Instructors in the same Art, I cannot find what Use there could be of Books, except in the hands of those who are to make Learning their Trade, which is below the Dignity of Persons born to Titles or Estates.
